                 Sets the maximum size of a single file in the log, in bytes.  
                 The value set for this parameter may not be larger than the
                 maximum unsigned four-byte value.
            </p>
      <p>
                 When the logging subsystem is configured for on-disk logging, the
                 default size of a log file is 10MB.
            </p>
      <p>
                 When the logging subsystem is configured for in-memory logging, the
                 default size of a log file is 256KB.  In addition, the configured log
                 buffer size must be larger than the log file size.  (The logging
                 subsystem divides memory configured for in-memory log records into
                 "files", as database environments configured for in-memory log records
                 may exchange log records with other members of a replication group,
                 and those members may be configured to store log records on-disk.)
                 When choosing log buffer and file sizes for in-memory logs,
                 applications should ensure the in-memory log buffer size is large
                 enough that no transaction will ever span the entire buffer, and avoid
                 a state where the in-memory buffer is full and no space can be freed
                 because a transaction that started in the first log "file" is still
                 active.
            </p>

                 The syntax of this parameter in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a
                 single line with the string <code class="literal">set_lg_max</code>,
                 one or more whitespace characters, and the maximum log
                 file size in bytes.
            </p>
      <p>
                 If the database environment already exists when this parameter is
                 changed, it is ignored. To change this value after the environment
                 has been created, re-create your environment.
